Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43238, here are decompositions:
- 31 + 43207 = 43238
- 37 + 43201 = 43238
- 61 + 43177 = 43238
- 79 + 43159 = 43238
- 271 + 42967 = 43238
- 277 + 42961 = 43238
- 337 + 42901 = 43238
- 379 + 42859 = 43238
Showing the first eight; more decompositions exist.
